Matters needing attention in the design of plastic flexible packaging
1. Aluminum plastic flexible packaging and aluminum paper flexible packaging: due to the opacity, the conventional color can be considered
2. Single layer polyethylene packaging: because it is transparent, you can consider using the color of the content as the complementary color of printing, and the color of the content can be used as the pattern background or as the decorative color (window color), as long as it depends on your design style
3. The color of liquid items can be used for the background color of flexible packaging, such as milk, soymilk, fruit juice, etc
4. The color of small solid particles can also be used for the background color of flexible packaging, such as coffee, monosodium glutamate, etc
5. The color of large solid particles is not good for the background color used in soft packaging. For example, if candied fruits have been dried, it is recommended to leave transparent windows on the packaging, or print full page opaque colors on one side, and only instructions on the back to make the contents transparent and visible
6 the driving pressure range of the pressure testing machine is 0.1 to 0.64 MPa. The bar code must have a background with obvious contrast. It is not allowed to use the content as the background, so as not to be read by the code reader
7. There are no tough regulations on words. As long as the contact surface with food is not printed, the artistry of words is the space for design to play
8. As far as possible, using more colors will appear more realistic, but as a result, 4. The interface on the plug-in controller must be turned off, and the power supply of the controller will go up. Generally, there are at least four sets of films, that is, four colors. To print realistically, it is best to produce seven sets of films for plate making, that is, seven colors for printing, of course, on the premise that the production cost can be borne
9. The color of the text is not listed separately, but summarized in other patterns
10. Text size: the trade name can be larger, but it still depends on the size of the packaging bag. It can also be artistically processed, that is, some text deformation and so on
11. The explanatory text can be smaller, but the minimum shall not be less than 2.5mm, otherwise it cannot be seen
12. All words should have a greater contrast with the background color, so that the two versions can be clearly readable
13. There are no tough regulations on problems such as exposure, which also belong to the category of design creativity
